4|lviP'RovEn/IENT IN TAPS ANDNozzLl-:s FOR OIL-CANS.

Specification forming part of Letters Patent No. 112,771, dated March 21, l871.

I, JABEZ A. BosTWIGK, of the city, county, and State of New York, have invented an Improved Form of Tap and Nozzle for Oil-Cans and other Vessels, of which the following isa specification N atnrc and Objects of thc Intention.

My invention relates, first, to the construction of a tap for oil-cans and other vessels which l shall be detachable from the can, and be simply and cheaply constructed of two pieces of met-al stamped up and united at the rim in a peculiar manner, to inclose a valve operated by a screw, as hereinafter described; and, second, to the use7 in combination with said improved tap, of a metallic threaded seat or nozzle, to be soldered over the mouth of the can or vessel, and which is closed when applied thereto so as to seal the same hermetically, but which is scored, so that an opening may be readily formed through the same when the contents of the vessel are to be discharged.

- Description of the Accompanying Drawing.

Figure lisa top View, in perspective, of my improved threaded nozzle secured over the mouth of an oil-can; Fig. 2, a top view of my improved tap; Fig. 3, a vertical section thereof in the line cc fr of Fig. 2, illustrating the tap and nozzle combined, with the valve opened; and Fig. 4, a similar section in line y y of Fig. 2, illustrating the valve closed.

General Description.

tured, but is deeply scored with an annular groove, c, in the center thereof, so that the center-piece within said groove may be readily decached and removed with a pen-knife blade, or by a blow thereon with hammer and nail.

Hence, when the can is filled with oil, it is hermetically sez led by simply soldering this improved nozzle over its mouth or opening, as illustrated in Fig.- lof thedrawin g.

D is a circular cup, forming the outer shellof the tap. It is struck up in one piece out of vsheet metal, and is formed with an open bottom, encircled by an annular ilange, which is threaded exteriorly and made to it and screw into the countersunk recess of the nozzle A, and with curved sides, which are pinched out at opposite points in the rim of the cup to form spouts E E. (See Figs. 2 and 3.) The rim of the bottom flange of the cup is bent inwardly to form an oifset, j', as shown in Figs. 3 and 4.

F is a circular countersunk lid or cover for the cup, which-is likewise stamped up from a single piece of sheet metal. The rim s of the lid projects with a slight curve, and iits closely within the rim t of the cup, which is then bent over and pinched down thereon, as illustrated in Figs. 2 and 4 of the drawing, so as to hold and secure it rmly. 'Ihe top of the open-bottomed cup D is thus closed by the countersunk lid F, secured thereon, its spouts E E alone being left uncovered.

Gr is a screw passing centrally through the lid, and through anut secured upon its under side.

His a circular cup-shaped disk, into which a leather washer or seat, K, is fitted to form a valve. This valve is secured centrally to the lower end of the screw G, soas to turn therewith. It is of such diameter as to cover fully the opening in the nozzle A, into which the tap is to be screwed. The screw G is of such length as that, when the valve H K is turned down. to close the opening in the nozzle, the head Gr of the screw will not project above the rim of the tap. (See Fig. 4.) The screw works loosely through its nut, so as to allow a slight horizontal play to the valve, and permit it to adjust itself closely over the aperture in the nozzle.

I do not claim the arrangement or operation of the valve Il K to open and close the nozzleA.

My invention relates to the form and con struction of the tap, and to the combination thereof with the nozzle A, as described, whereby I secure the following important advantages: My tap, from its simplicity of construction, may be manufactured at an extremely low cost. lt is detachable from the can, and may therefore be readily removed to permit a refilling of the can, or for use upon a second can tted with my lmproved nozzle; hence, in shipping a case of 011 contalning several `cans it is only necessary to furnish one nozzle therewith, as they one will suflice to empty all the cans. By its use, in combination with the scored nozzle A, the can may remain hermetically sealed until it reaches the consumer, who, by removing the tap, is enabled to readily open the nozzle, and, replacing it, to dranr out the contents of the can with neatness and dispatch, as required. The

Claims.

I claim as my invention- 1. As a new article of manufacture, thewithin-descrbed metallic tap for oil-cans and other Vessels, constructed of the open-bottomed cup D, threaded to screw into the nozzle of the can, the recessed or countersunk lid F, secured thereto, and. the valve H K, operated by a screw, G, working centrally through the lid, said parts being formed and combined substantially in the manner herein set forth.

2. In combination with the subject-matter of the first claim, the Within-described metallic, countersunk, scored, and threaded nozzle A, as herein set forth.

Witness my hand to this specification.
